Abstract (en)

[origin: EP3868795A1] Disclosed is a hydrogenated copolymer obtained by hydrogenating a copolymer which comprises an aromatic vinyl monomer unit and a chain conjugated diene monomer unit. When, among at least two hydrogenated copolymer-derived peaks in an elution curve measured by gel permeation chromatography of a sample containing the hydrogenated product, a hydrogenated copolymer-derived peak exhibiting a peak top with the earliest elution time is defined as a first peak and a hydrogenated copolymer-derived peak exhibiting a peak top with the second earliest elution time is defined as a second peak, the ratio of a standard polystyrene-equivalent molecular weight based on the elution time of the first peak (first peak molecular weight) to a standard polystyrene-equivalent molecular weight based on the elution time of the second peak (second peak molecular weight) is 1.50 or more. The second peak molecular weight is 1,000 or more.
